Wow. That was our reaction to Kenyan actress Lupita Nyong'o, who has been one of the very best-dressed actresses of this year's awards season, and her 2014 Oscars dress. She donned a princess-like, ice blue Prada confection and she was easily the prettiest starlet of the night.

Nyong'o, who wore bright colors, columns and capes at events this year -- which elevated her to instant style star -- went a totally different route tonight (March 2). She enjoyed her princess moment with the custom-made Prada, which was belted, pleated and flowed from the waist down.

Even with that sexy, plunging V neckline and backline, the dress was utterly precious and delicate. The color paired perfectly with her dark skin.

Gorgeous. Really, there is no other word for it.

Nyong'o even said that this shade of blue reminds her of Nairobi, so she just minted a new term and color in fashion -- Nairobi blue! Actually, it should just be called Lupita Nairobi blue, since she will forever be associated with this shade.

This was Nyong'o's Cinderella moment. Someone called her "Lupitarella" tonight, rightfully so.
